I started off with running ARBs on the FS until I found a way of stabalising the car without them. On tracks like Coventry (think about what you would get if you astro turfed the surface of the moon and left a few edges loose then made the track markings out of land mines
) the ARBs just make the car far far too unpredictable IMHO.
Admittedly I've not revisited the ARBs since going to permenant 4wd from a one way but then I'm never suffering from lack of pivot on the FS!
